It depends. If the initial investigation reveals that someone may be at fault with a level of negligence, or recklessness involved, then an investigation will follow and charges laid etc.
If someone has fallen asleep and killed themselves, it will be very brief. If they kill someone else and survive, different story. If they have a heart attack and kill someone or a few others, not much will happen.
One can only assume similar with aviation. The chap in the Jabiru that blasted off into atrocious weather, received a limited investigation.
